Does an electrical device need a big flow or a small flow to work? For example, a 100 W light bulb uses energy at a higher rate than a 60 W bulb; this means that the 100 W light bulb needs a bigger "flow" to work. Likewise, the rate at which your solar energy system "flows" power into your home is measured in watts.
